Let n weighted points be given in the plane. The inverse version of minisum circle location problem deals with modifying weights minimum cost, such that sum distances from circumference a C radius r, to is minimized. classical model this contains infinite constraints. In paper, mathematical finite constraints presented. Then an efficient method developed for solving problem.

This paper focuses on a refinement of the inverse Galois problem. We explore what finite groups appear as group an extension rational numbers in which only predetermined set primes may ramify. After presenting new results regarding extensions single prime ramifies, we move to studying more complex situation multiple from arbitrary size then continue by examining conjecture Harbater that minimal...

In this study, singular diffusion operator with jump conditions is considered. Integral representations have been derived for solutions that satisfy boundary and conditions. Some properties of eigenvalues eigenfunctions are investigated. Asymtotic representation eigenfunction obtained. Reconstruction the shown by Weyl function.

Magnetic induction tomography (MIT) is a new technique to image the electromagnetic properties of an object by mutual induction data of pairs of excitation and sensing coils. MIT has potential in visualization of metal flow for continuous casting mainly because of its potential to deliver images with high temporal resolution. A dynamic magnetic induction imaging technique is developed with the ...

 Abstract: This study deals with modeling of heat flux at the external surface of combustion chamber wall in an internal combustion (IC) engine as a function of crank angle. This investigation results in an inverse heat conduction problem in the cylinder wall. Alifanov regularization method is used for solving this inverse problem. This problem study as an optimization problem in which a square...
